found a bug from beginner sheet. If you choose beginner sheet and start clicking "No-Limit Fullring" and "No-Limit Shorthanded" buttons, the Overview sheets statistics go nuts.

There are also another minor bug in beta 0.61 release. After I installed it and manually re-imported my handhistory, my postflop aggressiveness value dropped from 2,5 to 1 on the beginner sheet.

Keep on rockin'
